Importers of Hard Rubber (Ebonite) — All Forms & Articles paid $192K in duties in July 2026 — an effective duty rate of 20% on $986K in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataHard rubber, commercially known as ebonite or vulcanite, is distinguished from soft vulcanized rubber by its high sulfur content and rigid, thermoset structure, making it suitable for electrical insulators, bowling balls, chemical-resistant linings, and specialty industrial components. The heading covers hard rubber in all forms — including waste and scrap — as well as finished articles, all under a single US tariff line (4017000000). Canada leads US imports, followed by China. Because hard rubber is a purely industrial material with no food, drug, or biological application, no mandatory admissibility review applies at the border.

Hard rubber is defined by a sulfur content typically exceeding 32% by weight combined with the rubber, producing a rigid, non-elastic thermoset material. Soft vulcanized rubber contains far less sulfur and retains elasticity. When composition data is unavailable, hardness testing (Shore D scale) and the article's lack of elastic recovery under deformation are practical indicators. CBP may request a chemical analysis certificate if the classification is disputed.
Yes — heading 401700 explicitly covers hard rubber in all forms, including waste and scrap, as well as finished articles, all under the single US line 4017000000. This contrasts with soft vulcanized rubber, where waste and scrap have their own heading (4004). Importers dealing in hard rubber scrap for recycling or reprocessing should confirm that the material meets the chemical definition of hard rubber to avoid misclassification into the soft-rubber scrap heading.
